I would take exception to the letter by Sally I. Keith as to Barak Obama not being a U.S. citizen and should show his birth certificate. She along with others who have doubts should check the Internet link:

The Fourteenth Amendment states that "all persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States." Since Hawaii is part of the United States, even if Barack Obama's parents were both non-U.S. citizens who hadn't even set foot in the country until just before he was born, he'd still qualify as a natural-born citizen.
Some have claimed that Barack Obama's Hawaiian birthplace doesn't qualify him as a natural-born citizen because Hawaii was not yet a state when he was born. This claim is wrong: Hawaii was admitted as the 50th state almost two years before Barack Obama's birth there (Aug. 21, 1959 for statehood vs. Aug. 4, 1961 for Obama's birthdate).
The Obama campaign produced his 1961 Hawaiian birth certificate on the Internet back in mid-2008. If anyone would like to look at the image of the document, please go to Internet link:
